KUALA LUMPUR: The Ministry of Energy, Green Technology and Water (KeTTHA) is

working closely with all state governments to prepare for the El Nino phenomenon.

Its minister, Datuk Seri Dr Maximus Ongkili, said the Water Crisis Committee had been

entrusted to monitor the situation and come up with appropriate measures to minimise the

impact of El Nino on the country.

"We have been advising all state governments to take appropriate measures to face the El

Nino phenomenon. We are working closely with the Department of Meteorology and the

Natural Resources and Environment Ministry to monitor the situation, as well as linking up

with relevant bodies monitoring climate change in the region," he told Bernama here.

El Niño is a band of anomalously warm ocean water temperatures that periodically

develops off the Pacific coast of South America. Extreme climate change pattern

oscillations fluctuate weather across the Pacific Ocean which results in fluctuating

droughts, floods, and crop yields in varying regions of the world.

There is a phase of El Niño, which refers to variations in the temperature of the

surface of the tropical eastern Pacific Ocean and in air surface pressure in the

tropical western Pacific shows by Diagram (a) and Diagram (b).

El Nino adalah satu kawasan di mana kepanasan suhu air laut yang meningkat

secara berkala di luar pantai Pasifik Amerika Selatan. Aliran perubahan corak iklim

yang melampau turun naik cuaca di seluruh Lautan Pasifik yang menyebabkan

turun naik kemarau, banjir, dan hasil tanaman yang berbeza-beza rantau di dunia.

Terdapat fasa El Nino, yang merujuk kepada variasi dalam suhu permukaan

tropika timur Lautan Pasifik dan tekanan permukaan udara dalam Pasifik Barat

tropika ditunjukkan oleh Rajah (a) dan Rajah (b).
